- Designed for easy torque calibrations
- Adapters measure 2 in from the center of the square drive to the center of the adapter opening
- Special heat treated alloy steel helps to increase strength and durability
- Box end wall thickness is specially engineered to provide strength while still allowing ample room for access to reach difficult fasteners
- 12 point box end allows for fine indexing, helping to improve speed and access
- Fits 4, 6 and 12 point fasteners
- Proto® torque adapters are designed with a center-to-center dimension of 2 in. This means that the distance from the center of the square drive of the mating torque wrench to the center of the fasteners is exactly 2 in. This constant dimension serves to simplify the process of calculating the torque applied.
